摘　　要：本文研究了一类具有无限时滞的α-型偏泛函微分方程测度伪型解的存在性和唯一性。 文中假设线 性算子部分在Banach 空间X 上生成紧的解析半群,然后利用分数幕算子理论和算子半群理论证明了方程解的存在唯一性,并将其应用于一类生物数学模型中,验证结论的正确性。In this paper, the existence, uniqueness of measure pseudo type solutions in the α-form for partial functional differential equations with infinite delay are investigated. Here we assume that the linear part generates a compact analytic semigroup on a Banach space X, the delayed part is assumed to be continuous with respect to the fractional power of the generator. Finally, an example of biomathematical model is presented to illustrate the main findings.
